Quinn glans gaunt @flfi G'URDON. G. WOLFE, OF TROY, NEW YORK.

Letters Patent No. 76,292, dated March 31, 1868 IMPROVEMENT IN COOKING-STOVE TANKS.

TO ALL WHOM IT MAY CONCERN;

Be it known that I, .GUR'DON G. WDLFE, of the city of Troy, in the county of Rensselaer, and State of New York, have invented newand useful Improvements in Cooking-Stoves, and in Reservoirs or Water-Tanks for Cooking-Stoves, and in the mode or manner of attaching or combining the same with'cooking-stoves; and I do hereby declare that the following is a full,clear, and exact description of the construction, arrangement, and operation of the same, reference'being hereby had to the accompanying drawings, and to theletters. of referen-c marked thereon, which-form andmake a part of this specification.

Like letters represent and refer to like or corresponding parts.

Figurel represents in perspective a view of a cooking-stove containing my improvements in the construction of the plates of the oven of cooking-stoves, also my improved reservoir or water-tank combined therewith, and each more fully described hereinafter.

Figure 2 represents a section of a cooking-stove, showing the manner in which my said reservoir orwater tank is arranged and combined therewith.

Figure 3 represents my said boiler, reservoir, or water-tank, showing the construction thereof, and more fuily'iiescfibed hereinafter.

Figure 4 represents another mode of combining my said reservoirwith a cooking-stove, and hereinafter described" and set forth.

' The natureof my said invention and improvements consists in so constructing, arranging, and combining,

with a cooking-stove, a reservoir or water-tank for such stoves, that a part thereof shall fit into and form a part I (if the top plate of such stove, and at same time rest and remain over and upon the flue or fiues in the rear end of such stove, as well as over thefiue passing from the fire-chamber 'over the oven to the exit-flue in the rear end of said stove, while atsame time a part or portion thereof shall extend downward from the topplate aforesaid, and against the-rear end vertical plate of such stove, or against a damper therein, in case it should be deemed best to "make'sucli damper-openings in such vertical end plate, therehy'heating the-bottom and side in part of suchcres ervoir, inthe manner substantially as herein descrihedand set forth.

It also consists in the employment and combination, with the oven of a cooking-stove, of corrugated plates upon the bottom, front, and rear parts thereof, in the manner and for the purposes substantially as herein described and set forth. I

It also consists in the arrangement of a damper in the rear and vertical end plate of a cooking-stove, and the combination of the same with the reservoir or water-tank of a cooking-stove, in the manner and for the purposes substantially as herein described.

It also consists in constructing a reservoir or water-tank for a cooking-stove, with a part or portion of the bottom thereof raised up or elevated within the said reservoir or water-tank, with the exit-pipe arranged in such part or portion in the manner substantially as shown at fig 3 of accompanying drawings, and substantially as and for the purposes herein described and set forth. i

It also consists in the removing of a part or portion of the rear end of the top plate of a cooking-stove, so as as to form an openingof suflicient capacity to receive and to contain a part of the bottom of a reservoir or water-tank,substantially as shown at fig. 2 of, the accompanying dra\vings, and herein described and set forth.

It also consists in the employment of a hot-air chamber, of the size of that part of such reservoir-or watertank hanging below the top plate of such stove, which shall communicate with the fiueor fines in the rear end of said stove, by means of a fine-opening and flue-plate, in the manner substantially as shown at fig. 4 of the accompanying drawings, and in the manner and for the purposes substantially as herein described and set forth. Having thus described the nature of my said inventign and improvements, I will now and here proceed to describe the construction, arrangement, and operation of the same, which is as follows, to wit: I construct my said reservoir or water-tank of tin, lined with copper, orof other suitable material, and in size to correspond with the cooking-stove where the same is to beused. The back part or portion of such reservoir projects and continues downward below the bottom of the front part thereof, in the manner substantially as shown at figs. 1 and 3 of accompanying drawings, The said reservoir or water-tank may be seen in perspect- I rates 2 ive at fig. 3. A is that part of said reservoir which projects downward from and below the top plate, 13, of the stove, and against the rear vertical end plate 0, containing the damper G, and whichmay thus be continued downward to any distance desired... D is that part of such reservoir which is fitted into the top plate 13, at the rear end thereof, a sufiicient portion thereof being removed so as to receive and-contain such water-tank, in the manner substantially as shown at fig. 2, and thereby permitting that portion of the bottom of said reservoir which receives and contains'the exit-pipe E, fig- 3, 'to cover the fine or fines in the rear end of the cookingstove, as well as to'v cover some part or portion ofthe flue over the topof the oven, if found expedient so to do, and at same time filling up the said opening in said top plate, so as to expose that part or portion of the bottom of said reservoir which is raised up and above the bottom part A, and marked F, figs. 1 and 3. The bottom itself of this part of my said boiler may be seeu at F, fig. 3, and it may be corrugated, as shown in said figure, which is for the purpose of increasing the heating-surface of said bottom part ofthe said reservoir, or it may be, constructed of an entirely smooth surface. .In this elevated part of said bottom of my reservoir, I arrange and construct the exit-pipe E, whichfwhen said reservoir is in its place upon said cookiirg-stove, is directly over the centre flue in the rear end of such stove, if there be. three or more fines used therein. If but two fines are thus constructed, then said exit-pipe will be over one of said fines, or somepart or portion thereof. The-upper part of such exit-pipe, E, is supported by a bracket, .G, extended out from and cast with the rim or cast-iron plate H, extending around the outer. edges of said reservoir, and to which thc"i-escrvoir-cover, I, is hinged, substantially as shown at figs. 1 and '3, which cover has and contains a recess, J, as shown at said fig. 3. From the upper bottom, F, tothe lower bottom, A, is constructed a plate, K, cast with said reservoir. This plate or part,'K, is that part or portion of my said reservoir which comes against or in contact with the damper or damper-opening C, shown at fig. 2, as aforesaid, audwhich part is constructed to fit the end plate C, or any flanges casttheredn, as seen at a, figs. land 4.

My said reseivoir is constructed in form, shape; and with the respective plates or parts, substantially as shown atfig. 3, and-when it is applied to, arranged, and combined with, a cooking-stove, it will be substantially as showuatfig'l. The fines at the top, in the rearend of the said stove, are exposed, and a part of the top plate, B, corresponding to that part of said reservoir to be fitted thereto, is removed, and the damper and damperopenings G in the vertical and rear end plate, C, of such stove are each and' all constructed, arranged, and combined substantially as seen at fig. 2. Another form-of arranging mysaid reservoir upon and with a cookingstove, as aforesaid, will appear upon'an inspection of the accompanying. drawings, at fig. 4-. thereof. With the exception of the employment of said damper, C, I useuu' elongated flue, L. with a flue-plate or strip, L, immei.

diatelyover such fiue-opening, substantially as seen at said'fi g. 4. This opening, L, permits the hot air to pass from the rear end of the said stoveinto a chamber,M,- outside of the rear end of the stove, one-side of which is formed or completed by means of that partof said reservoir which comes against the flanges or jambs a,.when said reservoir isapplied to the said stove, as aforesaid, while the bottom part, F, covers the upper part of said chamber,- M, when fitted and applied to and with the top plate B, substantially as aforesaid. To control the' passage of the heat into said chamber M,.I use the damper N, same figure'.

When my said reservoir is applied to a stove, substantially as shown at fig. 1, the damper C may be open.

or closed. If it should be necessary, for the rapid heatingofwater in my said reservoir, to bring more heat to bear upon such reservoir, then-said damper may be open, but for the usual and ordinary purposes of heating water it will not as necessary that said damp er, 0', should be open, for the action of the heat against that part of said: reservoir which fits into a. recess in the said top plate of the stove, and over said flues, as aforesaid, together with the action of heat upon the exitpipe B, will be sufiicientfo'r all practical purposes, without the use of said damper, and yet if moreheat should be desired against the said reservoir for rapid heating of water in said reservoir, then said damper will be opened; otherwiseit will remain closed, which is done by means of a corresponding slide, in the usual way of opening and closing sliding dampers. I

' I prefer to construct my said reservoir wholly of cast iron, but it is'manifest that, as I have'hereinbefore stated, it may be constructed of tin, copper, orother sheet metal, with one or more thicknesses, casting only the rim H and cover I. 4 I

vBy constructing a'reservoir substantially as aforesaid, I am enabled to getmoresnrface for heating of the water therein, at same time making a reservoir of more strength and utility thananyheretofore made, and also greatly economize room for the use of such stove, for it will at once appear, onexamination of said drawings, thatat least one-half of the thickness of the reservoir is saved. 1- also greatly economize the use'of fuel, as more surface is exposed to the actionof the heat upon said reservoir. It is also more'convenient to pour water into such reservoir or to dip therefrom, than it would he were the whole reservoir above the top plate of the said Steve. Water in said reservoirmay' be-lieated very hot, more so than I have any knowledge orinformatiou of concerning any other k'ind'of reservoir or tank, and differently combined and arranged with the cookingstove. A warmingcloset may be arranged underneath said bottom part, A, of said reservoir, in the usual wayand manner; The plate, K, may be. corrugated in the same manner as the'upper bottom plate F, if deemed best so to construct the same, and thus give more heating-surface.

At fig. 1 may be seen the inner plates, 0, of the-oven. The bottom plate 0, the rear end plate 0, and the front plate 0" are each and all constructed with corrugations, as shown at said figure, and its accompanying section marked Figure 1. These plates are thus constructed for the purpose of obtaining more heating or baking-surface.' It-is manifest that such corrugations willlargely'increase such surface of said plates, and thus facilitatebaking or roasting. At the same'time such plates thus constructed are much more strong than were they constructed even or smooth, in the usual way, and of course they may behest of less thickness,and thereby save in the use of iron, and give astronger plate, as well as one that .will permit th'eheat to pass through the same quicker than it would were it thicker, and therebyrender'the oven ready for usc in much less time.

Having thus-described the'naturefcoustruction, and operation of my said invention and improvements;

what I claim, and desire to secure by Letters Patent of the United States,'is-

1. The reservoir or water-tankA, constructed:with an upper bottom, F, and alower bottom, A, and intermediate plate K, and exit-flue 1 each being arranged and combined in the manner and for the purposes s1ibstantially as herein described and set forth.

2. I also. claim the combination of the-reservoir'or'water-tank A constrncted substantially as herein described, with a cooking-stove, having a part or portion of the rear end of the top thereof removed, substantially as shown at fig.--2 of the accompanying drawings, so as to receive and contain the upper part or bottom, F, of said-reservoir, in themanner and for the purpesessubstantia'lly as herein described andset forth.

3. I also claimtheemployment of the damper 'O in the upper part of th -rear and vertical end'plate of the cooking-stove, incombinatioh with the vertical flees in the rear end of the stove, and with that part or pertioniof said reservoir extending below the top 'plate of said cooking-stove, as seen at fig. 1 of accompanying drawings, and in the manner and for the purposes substantially as herein described and set forth.

4. I claim the employment of theriue-opening L, flue-plate L, and flue-chamber M,in combination with, the reservoir A, in the manner substantially as herein described. set forth.

5, Iclaim theemployment and arrangement sf a reservoir or waterank with aeooking-stove, so that a part thereof shall be above the top'plat f the stove, and over the vertieal flue or lines in the rear end thereof,

and a part'below such top plate, in the'manner substantially as shown at fig. 1 of the aceompanying drawings.

In testimony whereof, Ihave hereunto set my hand, this 5th day of February, A. D. 1868.
